Many enzymes are allosterically regulated. Our ability to manipulate these structural changes is limited. Here we install an allosteric switch into the kinesin-1 microtubule motorin vitroand in cells. Kinesin-1 is a heterotetramer that accesses open active and closed auto-inhibited states. The equilibrium between these centres on a flexible elbow within a complex coiled-coil architecture. We target the elbow to engineer a closed state that can be opened with ade novodesigned peptide. The alternative states are modelled computationally and confirmed by biophysical measurements and electron microscopy. In cells, peptide-driven activation increases kinesin transport, demonstrating a primary role for conformational switching in regulating motor activity. The designs are enabled by our understanding of ubiquitous coiled-coil structures, opening possibilities for controlling other protein activities.One Sentence SummaryDe novopeptide and protein design are used to engineer an allosteric switch into kinesin-1 motorsin vitroand directly in cells.
